Ask BIOS / BIOS Repair Lenovo X1 Extreme Gen 2

[HELFERLINE GmbH]

Hello, the Laptop does start with Backlight, but doesn't Display anything.

I already tried the BIOS that was posted here:

BIOS - Lenovo Thinkpad P1 Gen2 - 18809-1

Lenovo Thinkpad P1 Gen2 - 18809-1 Boardview BIOS Lenovo Thinkpad P1 Gen2 - 18809-1 Boardview.brd Schematics

vinafix.com

Using this BIOS however leads to the Laptop not starting at all, being stuck at 290mA.

I will post the old Bios file here and also attach the PCB Number.

If possible to repair BIOS would be great or new Bios.

Thank you !
